The invention relates to a method for producing a bearing ring (2, 3) for a roller bearing (1). Furthermore, the invention also relates to a rolling bearing (1) with two bearing rings (2, 3), namely an inner ring (2) and an outer ring (3), which are formed of a ring material, wherein the inner ring (2) on an outer peripheral surface and the Outer ring (3) on an inner circumferential surface in each case a raceway (4, 5) for guiding rolling elements (6), wherein the rolling elements (6) roll on the respective raceway (4, 5), wherein the annular material at least 1.29 to 2 Wt .-% carbon, 0.5 to 0.6 wt .-% silicon, 0.2 to 0.4 wt .-% manganese, 3.8 to 4.8 wt .-% chromium, 2 to 5 wt. % Molybdenum, 3 to 5.1% by weight of vanadium, 5 to 14.3% by weight of tungsten and 0 to 11% by weight of cobalt or alternatively 0.5 to 2% by weight of carbon, at most 0.035 % By weight of sulfur, 3 to 5% by weight of chromium, 1 to 4% by weight of vanadium, 1 to 12% by weight of tungsten and 2 to 12% by weight of molybdenum, where at least one of the two bearing rings ( 2, 3) at least by an additive manufacturing process hergestel lt is. |
